How To Replace a Peloton Crank Arm

If you’re riding a Peloton and your crank arm comes loose, don’t worry – it’s an easy fix. All you need is a new crank arm and a few tools, and you’ll be back on the bike in no time.

Here’s what you’ll need:

  • A new Peloton crank arm.
  • A set of Allen wrenches.
  • A Phillips head screwdriver.
  • A hammer.

Step By Step Process:

  1. First, remove the old crank arm by unscrewing the retaining bolt with an Allen wrench. Be sure to hold onto the end of the crank arm as you remove the bolt, as it may come off with the unscrewing force.
  2. Next, take your new crank arm and insert it into the crank arm socket. Make sure that it is fully inserted and flush with the socket.
  3. Now, take your Phillips head screwdriver and screw the new retaining bolt. Be sure to tighten it securely, but be careful not to over-tighten as this may strip the threading.
  4. Finally, grab your hammer and tap on the end of the crank arm until it is seated firmly in place.

That’s it! You’ve now successfully replaced your Peloton crank arm. Get back on the bike and enjoy your ride.

Why Does My Crank Arm Keep Falling off?
